问题描述

我正在构建一个 Ionic 应用程序,我想在其中使用 cordova 相机插件,因此我输入:

ionic cordova plugin add cordova-plugin-camera

然后我做:

npm install --save @ionic-native/camera

在这里,我收到了以下警告:

npm WARN @ionic-native/camera@5.0.0 requires a peer of @ionic-native/core@5.0.0 but none is installed. You must install peer dependencies yourself.

npm WARN optional SKIPPING OPTIONAL DEPENDENCY: fsevents@1.2.7 (node_modules/fsevents):
npm WARN notsup SKIPPING OPTIONAL DEPENDENCY: Unsupported platform for fsevents@1.2.7: wanted {"os":"darwin","arch":"any"} (current: {"os":"linux","arch":"x64"})

之后,当我在 app.module 和提供者列表中包含相机插件时,我收到以下消息:

Error: Invalid provider for the NgModule 'AppModule' - only instances of Provider and Type are allowed, got: [StatusBar, SplashScreen, [object Object], ?[object Object]?]

解决方案


由于 Ionic 4 的发布,为 Ionic 3 安装 Ionic Native 插件需要在为 Ionic 3@4安装时附加。因此,要解决此问题,请使用 卸载插件npm uninstall --save @ionic-native/camera,然后重新安装,npm uninstall --save @ionic-native/camera@4问题将得到解决。
